Excellent visual layout, suffers from stability issues.
Actually pretty good, especially for a free app. The interface allows for easy switching between lenses and camera, and using the sliders to choose distance, aperture and focal length makes for a very quick to use app. This does mean, however, that choosing a specific distance can be difficult for those without steady hands since the sliders are very sensitive.
I have tried the other free DOF apps, nothing comes close to the usability of this one. Customizable, fast and easy to read - if it didn't crash every few minutes (particularly when switching lenses in the menu) I'd give it a solid 5 stars, since I couldn't ask for more from a free app. Definitely worth a try.
